Abstract: An active mixer for frequency conversion used in a wireless communication system improves conversion gain and noise figure by improving switching characteristics of a mixer using a LO signal without requiring additional power consumption of an active mixer block. Further disclosed is a method for improving conversion gain and noise figure of an active mixer. The active mixer includes a switching stage for receiving a LO signal and selectively performing a switching-on/off operation for frequency conversion, a body signal generator for generating a body signal to be applied to a body of an NMOS transistor of the switching stage based on the LO signal, and a voltage controller for controlling the body signal generator to selectively apply the body signal to the body of the NMOS transistor based on to the switching-on/off operation of the switching stage to control a threshold voltage of the transistor of the switching stage.

Abstract: Disclosed is a method for estimating twin defect density in a single-crystal sample, including: (A) etching the observed surface of a single crystal to form etch pits; (B) selecting bar-shaped etch pits caused by twin defect; (C) from the long-axis direction lengths of the etch pits caused by twin defect, estimating the twin defect density by using the following equation: twin defect density=Σkx′i/area of sample, wherein 2≤k≤3, and x′i is the long-axis direction length of an etch pit caused by the i-th twin.

Abstract: Disclosed are a system and method for endpoint discovery based on the Data Distribution Service. The endpoint discovery system includes: a discovery information collecting part that collects first discovery information about a first domain network in which a plurality of endpoints including a first endpoint are interconnected, and that collects second discovery information about the first domain network after a preset period of time after collecting the first discovery information; and an endpoint discovery part that detects a second endpoint that is added to or deleted from the first domain network by comparing the first discovery information and the second discovery information, and that discovers the first endpoint having the same topic information as the second endpoint and transmits information about the second endpoint to the first endpoint.
